Created bootable USB stick with Windows 7 iso, via 'Microsoft USB/DVD Download Tool' (on alternate Windows 7 system) I'm having getting my USB stick recognized as a bootable device (installing windows 7 onto a system that came with windows 8.1 pre-installed, no optical drive) Make sure to change the BIOS back to boot from your hard drive in future (and, whilst you’re there, check the BIOS front screen to ensure the BIOS version number is correct!).Acer Aspire E15 :: Can't Boot From USB (UEFI) Feb 18, 2015
The BIOS should now install and reboot your Acer. Go into C: (which is actually your USB memory stick) and find the BIOS files you saved earlier. I should have maybe said earlier that if you’re not literate with DOS, then you may struggle at this point 😉 FreeDOS will now have started and you’ll have a standard DOS screen. You will now be presented with a list of boot options – select option 5 (FreeDOS Live CD). The FreeDOS screen will appear with an option to select a default option. Your Acer should now boot from the USB stick. Once in the BIOS select the Boot Menu and move the USB HDD to the top of the list (using F5 and F6 to move them up and down). Reboot the Acer and press F2 at the “splash screen” to go into the BIOS settings. Now copy the BIOS files onto the USB drive as well. Click on “OK” and FreeDOS will be installed onto the USB drive. At the bottom of the window ensure the “Type” is “USB Drive” and the “Drive” is the drive letter of your USB memory stick. It will prompt for a “Distribution” – change this to “FreeDOS”. Ensure your memory stick is plugged in and run UNetbootin. A download of the latest BIOS from Acer. Simply click on the option to download the latest Windows version. 
A download of UNetbootin – this is a free program that will create a bootable USB device with one of a number of downloadable operating systems, including any your own. Now, and this is where I went wrong initially, the USB memory has to be formatted as FAT32 and not NTFS. No idea why as the files took up 3.2MB in total. I read somewhere that recommended a 4GB one. And that when I say USB memory, I also mean USB drive. That means putting DOS on a USB stick and booting from it.īear in mind that I have a Windows XP A150 Aspire One. And not the Command Prompt DOS-a-like that Windows offers. In a nutshell, the BIOS has to be upgraded via DOS. In the end I found a combination of advice was the best solution. I couldn’t find anything on the Acer site on how to do it, although they offer the BIOS updates, but I did find various forums and blogs where it’s been discussed. As much as I hate doing BIOS updates, due to the possibility of catastrophic problems, I decided to give it a go. The BIOS on my Acer was horribly out of date and the change logs showed that a lot of useful fixes had been implemented since.
